As specific pharmacological inhibitors, the following were preincubated with MEC1 cells prior to infection with H. pylori: PP2 blocking SFKs (40); STI-571 inactivating Abl, platelet-derived growth factor receptor (PDGFR), and c-Kit kinases (41); and dasatinib targeting SFK, Abl, c-Kit, PDGFR-α, PDGFR-β, and ephrin receptor kinase (42). Here, PDGFRB is linked to infection.
